球墨鑄鐵由於其糊狀凝固的特徵決定所生產(chǎn)的鑄鐵由於補縮不好經(jīng)常產(chǎn)生縮孔、縮松等缺點，為了能在鑄件生產(chǎn)以前預測這些缺點情況，早在印年代國內外就開展了鑄造過程數(shù)值類比。鑄造過程數(shù)值類比是使用數(shù)值類比技術，在計算機虛擬的環(huán)境下類比實際鑄件形成過程，包括金屬液體的充型過程、冷卻凝固過程、應力形成過程、判斷成型過程中主要原素的影響程度，預測**、性能和可能出現(xiàn)的缺點，為優(yōu)化工藝減少廢品提供依據(jù)。節(jié)能要求導致基本上重新設計零件，以達到重量輕、效率高，這就必然要提醒設計者集中注意材料。

管道的埋設深度應根據(jù)冰凍程度、外部荷載與其它管道交叉等因素確定。在通常情況下，埋設深度可在冰凍線以下0.2米處，并符合如下條件：當管徑大于100mm時，管頂小埋深為1.20米。設計溝槽底寬通常為管外徑加0.5米，并根據(jù)土質狀況，確定開挖坡度（i）球墨鑄鐵管與其它管材一樣，均勻流的沿程水頭損失為hf=λ/dv2/2g，所不同的只是“λ”（水力摩阻系數(shù)），即水頭損失可按原鑄鐵管局部阻力損失計算。球墨鑄鐵管的出現(xiàn)為我國供水事業(yè)提供了一種性能優(yōu)良的新型管材。為了在工程中更好的應用球墨鑄鐵管，設計與施工人員應熟悉球墨鑄鐵管的特性，不斷地發(fā)現(xiàn)問題并加以解決，使設計更加合理、施工更加規(guī)范，使新型管材在供水工程中發(fā)揮更大的作用。

style="text-indent:25px">球墨鑄鐵管是鑄鐵管的一種。質量上要求鑄鐵管的球化等級控制為1-3級（球化率》百分之八十），因而材料本身的機械性能取得了較好的改變，具有鐵的本質、鋼的性能。退火后的球墨鑄鐵管，其金相**為鐵素體加少量珠光體，機械性能良好，防腐性能優(yōu)異、延展性能好，密封效果好，安裝簡易、主要用于市政、工礦企業(yè)給水、輸氣，輸油等。在鐵素體和珠光體基體上分布有一定數(shù)量的球狀石墨，根據(jù)公稱口徑及對延伸率的要求不同，基體**中的鐵素體和珠光體的比例有所不同，小口徑的珠光體比例通常不大于百分之二**口徑的一般控制在百分之二十五左右。關于離心球墨鑄鐵管的小知識有哪些？</p><div

球墨鑄鐵管的維護保養(yǎng)可以說要一直從其選型開始，在項目開工前我們就應該對所需要用到的部件，如管材件、膠圈、彎頭等就行一次肉眼目測的外觀檢查，避免使用帶病的部件。二個保養(yǎng)的關鍵點是驗收工作時間我們應該著重注意到影響長期穩(wěn)定運行的承插口膠圈下管（排管）等，要力求在這幾方面的承口沒有雜物。膠圈已北橡皮錘砸實不翹不扭，均勻地卡在槽內。球墨鑄鐵管的維護保養(yǎng)過程中，由于動管軸心線是深埋在地下的，因此遇有傾斜角時，要小心，若阻力過大，切勿強行開挖，以防橡膠圈扭曲。球墨鑄鐵管在冬季的維護還需要注意用熱水預熱，以減少硬度，迅速安裝。
